An Eye-Movement Study on Text Font Size Design Rules in the Digital Learning Resources

摘要

A total of 100 college students were randomly divided into 10 equal groups, using different text font sizes (12pt, 18pt, 24pt, 28pt, 36pt) under different rendering devices (computer screen, iPad) to learn. The eye tracker is used to record the learner's visual cognitive process in real-time, and the learner's learning effect is tested. The results show that: (1) No matter what kind of rendering device is used, 18pt and 24pt text are most beneficial to learners, not only saving the learners' visual cognitive resources, but also improving their learning effect. (2) There is no significant effect on the visual cognitive process and the learning effect during text learning under different rendering devices (computer screen, iPad).
